Dear All, I'm getting a error while trying to apply the BreastCancer dataset (package=mlbench) to kknn (package=kknn) that I don't understand as I'm new to R. The codes are as follow: rm = (list = ls()) library(mlbench) data(BreastCancer) library(kknn) BCancer = na.omit(BreastCancer) d = dim(BCancer)[1] i1 = seq(1, d, 2) i2 = seq(2, d, 2) t1 = BCancer[i1, ] t2 =

Dear All, I'm having just a little terminology problem, relating the language used in the Hosmer and Lemeshow text on Applied Survival Analysis to that of the help that comes with the survival package. I am trying to back out the values for the baseline hazard, h_o(t_i), for each event time or observation time. Now survfit(fit)$surv gives me the value of the survival function, S(t_i|X_i,B),

Hi, I am looking for some help concerning the npudens function in the np package. I am trying to find a kernel density function of a multivariate dataset and the density evaluated at each of the 176 points. I have 2 continuous and 3 ordered discrete variables. My sample size is 176. So edata is a 176x(2+3) data frame, while tdat is a 1x(2+3) vector. bw_cx[i,] is a 1x (2+3) vector

I'm in teaching mode, kernel densities. {History: density() was newly introduced in version 0.15, 19 Dec 1996; most probably by Ross or Robert } When I was telling the students about different kernels (and why their choice is not so important, and "equivalent bandwidths" etc,etc) I wondered about the "Cosine" in my teaching notes which is defined there as k(x)

Epanechnikov kernel works if option canonical=TRUE, however it would be good to know why it does not for for canonical=FALSE (default). Sorry for craetaing maybe useless thread. Best regards, Ondra. [[alternative HTML version deleted]]

Hi, i would like to do a local linear regression but with a user-defined function f(x,y) as kernel. (not the typical Gaussian or Epanechnikov kernel function but some similar function). More, would it be possible to do a local linear regression by adding weights to the (x,y) data points? Many thanks in advance. -- View this message in context:

These errors are because not having glusternw assigned to the correct interface. Once you attach that these errors should go away. This has nothing to do with the problem you are seeing. sahina any idea about engine not showing the correct volume info ?

Hello, my name is Carsten. This ist my first post to R-help mailing list. I estimate densities with the function "density" out of the package "stats". A simplified example: #generation of test data n=10 z = rnorm(n) #density estimation f=density(z,kernel="epanechnikov",n=n) #evaluation print(f$y[5]) Here I can only evaluate the estimation at given

Hi, I am trying to use quantile regression to perform weighted-comparisons of the median across groups. This works most of the time, however I am seeing some odd output in summary(rq()): Call: rq(formula = sand ~ method, tau = 0.5, data = x, weights = area_fraction) Coefficients: Value Std. Error t value Pr(>|t|) (Intercept) 45.44262 3.64706 12.46007

He folks=) I want to check whether a coefficient has an impact on a quantile regression (by applying the sup-wald test for a given quantile range [0.05,0.95]. Therefore I am doing the following calculations: a=0; for (i in 5:95/100){ fitrestricted=rq(Y~X1+X2,tau=i) tifunrestrited=rq(Y~X1+X2+X3,tau=i) a[i]=anova(fitrestricted,fitunrestricted)$table$Tn) #gives the Test-Value } supW=max(a) As anova

Please, do not delay this "Important" multiple security update. See https://rhn.redhat.com/errata/RHSA-2009-0225.html for more info. This update is "5.3" kernel but has been released as security update too. RHN pushed this kernel one day ahead of rest of 5.3 packages (on my servers). RH maintains API and ABI (!) compatibility so there is no problem to use this kernel

Hello! Does anyone now if there exist a function that would compute a "null space" (or "kernel" - "Ker") of a matrix and maybe also one that would compute an "image" ("Im") of a matrix. I tried R-site search and google, However I found notnihg useful! Thanks for any sugestions! I am also not sure what an "image" of a matrix is, so

Hi all, I'm new on this List, I'm having troubles with samba at share from Linux <Gentoo Ker 2.4.20> to Win2k (Samba version 2.2.8a).

Does anyone have a guess as to where I should be looking to fix this? I can run wbinfo -u wbinfo -g and all the names come up right. Kinit works and I get a Ker ticket.. This is an Ubuntu 14.04 with samba 4. THIS IS THE FIRST LINUX COMPUTER I HAVE EVER BUILT!!!!!!! I knew absolutely ZERO about linux last week so I don't even know how to explain the issue. What I want to do is

Hi, i've migrated a debian box into ads, most people can work as they should, some users eg which are not part of the domain can not authenticate themself, the log says NT_STATUS_INVALID_COMPUTER_NAME . After reading all the howtos i noticed that wbinfo -t doesn work, the output is: #wbinfo -t checking the trust secret via RPC calls failed error code was NT_STATUS_INVALID_COMPUTER_NAME

Dear all, I am using np package in order to estimate a model with Klein and Spady estimator. To estimate the model I use KS <- npindexbw (xdat=X, ydat=Y, bandwidth.compute=TRUE, method="kleinspady", optim.maxit=10^3, ckertype="epanechnikov", ckerorder=2) and to estimate beta hats standard errors I use KSi <- npindex(KS, gradients=T, boot.num=300) vcov(KSi) This is

Dear all, I am trying to use the np package for the estimation of a model with Klein and Spady's semiparametric estimator.
